It is possible to become pregnant with a ground glass nodule of 8 mm without any adverse manifestations. It is usually possible to become pregnant with a ground glass nodule that is less than 1 cm in diameter, or with a diameter greater than 1 cm and a low density that may be in situ or minimally infiltrated. Because ground-glass nodules progress slowly and do not rapidly progress to advanced stages while pregnant, they can usually be reviewed at the end of pregnancy. Breast and ovarian cancers are sex hormone-dependent tumors that may be stimulated by elevated estrogen or progesterone levels during pregnancy. Lung ground glass nodules, on the other hand, are not hormone-dependent tumors and are not usually affected by estrogen or progesterone. Having a ground glass nodule 8 mm usually has no effect on pregnancy, but should be reviewed regularly in the hospital, as long as there is no significant change in the nodule, there is no need to worry too much.
